Bathymophila callomphala is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.
The nucleus is smooth, the subsequent 2 whorls are microscopically spirally striate, crossed by weaker growth-striae.
The last 2½ whorls are smooth, with only very faint, traces of growth-striae and spiral striae, but with a row of oval beads, just below the conspicuous suture.
The shell varies in altitude, in the presence or absence of the yellow subsutural line and especially in the characters of the umbilicus, which is either closed, or more or less open.
The rhachidian tooth has a subquadrate body, narrower in front, with concave upper and convex basal margin.
